Question

Which property justifies the statement?

If x = y + 2 and y + 2 = 8, then x = 8.

Transitive Property of Equality

Addition Property of Equality

Symmetric Property of Equality

Subtraction Property of Equality

Answer 1

transitive property of equality because you substituted x by 8

Answer 2

In tis question it is given that,

If x = y + 2 and y + 2 = 8, then x = 8.

Let's check out transitive property which states that

If

`a=b \ and \ b=c`

Then,

`a=c`

In this question,

`a=x , b=y+2,c=2`

SO we can say that the given expression follows transitive property of equality .

And the correct option is the first option .
